Our 2011 Holiday Gift Guide tries to hit you with gift recommendations at all different price points, and this one may be the least expensive. Radio Shack is selling a bunch of 4G Android smartphones for free, with two-year contract, this holiday season. You can get devices like the Samsung Stratosphere for Verizon, Samsung Infuse 4G for AT&T, and the HTC EVO Design 4G for Sprint. All of these devices support faster data speeds, and at a price of free, they're a tremendous deal.

"Sprint worked closely with HTC after reports emerged of a potential issue that could allow malicious third-party apps to compromise data on Android devices made by HTC," the carrier said in a statement. "We urge all users to install the update promptly."
